Abstract:Cordioli et al. and Krennmair et al. reported that rehabilitation with mandibular overdentures anchored to a single implant could be a therapeutic alternative for elderly patients experiencing discomfort and functional difficulties with conventional mandibular dentures. But the problem that a treatment period lasted for a long time was not solved. The present article is a case report of 86-year-old woman who treated with mandibular overdenture anchored to a single implant and a so-called early load was done and it could get good progress.
She consulted our clinic because of the pain due to a mandibular denture in March 2003. Her mandible was edentulous with severe resorption and mandibular denture was instable. In the maxilla only right canine and right first premolar remained, and partial denture was attached. In April she received a new mandibular complete denture but she complained that she could not eat stiff food. Informed consent about a single-implant-supported overdenture, considering her age and economic condition, was obtained and then in July a single surface-modified implant of 13 mm in length was placed at the mandibular midline. Since initial stability was good, a healing abutment was attached immediately. Healing process was good and one month later a healing abutment was replaced with a ball abutment and then a function as implant supported overdenture was given. After that retention and stability of the mandibular denture improved remarkably. She could become to eat many kinds of food and got a great satisfaction. At 1 year after loading peri-implant soft tissue was healthy. The radiographic examination revealed a stable situation.
